摘要：
The role electron nonextensivity may play on the energy carried by the ion-acoustic (IA) solitons is examined. A Korteweg-de Vries (K-dV) equation is derived. It is found that an increase of the nonextensive parameter q leads to a decrease of the soliton amplitude and width. The soliton energy is depleted as q increases. (c) 2014 Elsevier B.V.
